Dissolved carbon dioxide levels in the oceans are rising and this is causing a drop in the pH (ocean acidification). This potentially effects all marine organisms, including those in polar regions. Sea ice algae are naturally exposed to a wide range of pH and CO2 concentrations, particularly during the ice formation and melting cycles. However, all studies so far have shown ice algae to be quite resilient to change. This includes the effects of co-stressors such as light, iron and temperature.
